Hey, hey, hey. Isaiah, can you hear us, brother? Can you hear me? I got nowhere. I don't have anything. No idea what happened. I don't know if he's I can't tell if he's breathing or not. >> Get them back. Have them screw back. >> I can't tell if he's breathing. >> A deputy is down on a residential street in Jurupa Valley, California. And the people trying to save him don't know if he's still alive. What happens over the next 4 hours pulls in more than 100 officers across two counties and ends with a gunfight on a freeway that neither side walks away from clean. December 29th, 2022. Shortly before 2:00 p.m., Riverside County Sheriff's Deputy Isaiah Cordero, 32 years old, a motor enforcement deputy who'd only finished his motorcycle training 3 months earlier, pulls a truck over in the 3900 block of Golden West Avenue. >> Your driver's license and registration. >> My license is in my bag. >> I'm sorry? >> My license is in my bag. >> Okay. >> Can I grab it? >> Yeah. >> It's the most ordinary exchange there is. Seconds later, it isn't. >> No. Can we get this off? >> Get them back. Have them screw back. >> I can't tell if he's breathing. >> Get my AED. Nago. AED. >> AED now. >> Don't touch his right side. Got it. >> Can we get somebody to hold his head? >> Neighbors who heard the shot are the first ones at his side. Cordero is rushed to Riverside Community Hospital. He doesn't survive. The truck and the man driving it are already gone. Investigators cross-reference Cordero's own body camera against license plate cameras in the area and identify the driver, 44-year-old William Shay McKay. Less than 2 hours later, an off-duty officer spots his truck heading toward the freeway. And what started as a search becomes a pursuit stretching across the 210, the 60, and the 15. >> We got to pin him. Request if the spikes coming from the shoulder or center divider. >> Bearcat coming up behind you guys. >> Bearcat is approaching you at half a mile until you fell number three lane speed up the car. >> Dozens of patrol units, spike strips, and armored BearCat brought in specifically to end this on the department's terms, not his. >> The front two are deflated. Successful spikes. >> Same tire is smoking coming out of the rear tire. Just lost it. The driver's side rear tire. >> Make sure our speed's correct before we try that pit. We may be going too fast now. >> Even running on rims, he doesn't stop. For nearly an hour, deputies manage the pursuit like a moving hostage situation, clearing civilian traffic out of the way one exit at a time because a man who's already killed one officer is now doing 80 through rush hour. >> This dude is a danger to all these poor people up here. >> I want two waves. I want a primary pursuit package backed up by the second unit wave of ES units. I've got about seven or eight with me and that's plenty right now. >> Near the I-15 and 5th Street overpass in Norco, a mechanical failure does what the spikes couldn't. McKay's truck goes down. Deputies move the BearCat in and pin it. >> Clear the area. Suspect has a handgun and is shooting. >> Suspect is shooting a handgun. >> Get ready, buddy. Get ready. >> Shots fired. Shots fired. >> Deputies return fire. When it stops, McKay is down and the scene is being called secure over a dozen overlapping radios at once. The released footage states that officers fired 79 rounds and that McKay was struck 12 times, six to the head, one through the lungs, one that severed his spinal cord. Those specific figures come from the narration attached to the released video, rather than a separately published autopsy report. So, they should be treated as reported, not independently confirmed by a document this investigation could locate. A search of his truck turns up the gun used to kill Cordero, a bag of a white powdery substance, several fraudulently used credit cards, and a membership card tying him to an outlaw motorcycle gang. McKay's record goes back to 1999. Assault with a firearm, 3 years served. In 2005, a robbery where he and an accomplice choked and smothered two victims before stealing $3,700, 13 more years. In 2021, he held a woman against her will over an accusation she'd burglarized his home, bound her and her mother with duct tape, and threatened to kill them. She escaped and flagged down deputies. When they caught up with him 2 days later, his accomplice stabbed a police K9 during the arrest. He represented himself at trial. A judge convicted him of false imprisonment, evading police, and criminal threats, but acquitted him of kidnapping, ruling the victim was never forcibly moved. It was his third strike. Prosecutors asked the court to hold him without bail. The judge set it at $500,000, later reducible to 10% under the county's own bail schedule, and let him post it using property instead of cash. He made bail, got arrested again on a drug charge, made bail again, then simply didn't show up for sentencing. A warrant went out. It was still active months later when Deputy Cordero pulled him over for a truck with no rear license plate. In the aftermath, Riverside County officials, Cordero's family, and the Chino City Council publicly called for the judge's removal, arguing the bail decision put McKay back on the street. The San Bernardino Superior Court's response was that judges have no authority to override another judge's ruling. That dispute over accountability was never legally resolved. It remains a political argument, not a court finding. One week after his death, Isaiah Cordero was laid to rest. His mother spoke at the service. >> Our son is gone. We hurt so much. My dearest Isaiah, you were taken too soon. And I we do not know how we are supposed to carry on without you. >> Isaiah Cordero, ID number 5662, end of watch December 29th, 2022. Motor 38, 70 Isaiah Cordero. Rest in peace. We have it from here. >> More than 3 years later, no single public report has closed out every detail of what happened on that freeway. And as recently as 2026, records requests were still being filed for footage and files connected to this case that have never been made public.
